       3. A tape cassette storing case according to  claim 1 ,
 wherein when two of the storing case main bodies including a first main body and a second main body are stacked so that the second side surface in the first main body is superposed on the second side surface in the second main body, said plurality of ribs in the first main body is capable of engaging with said plurality of ribs on the second main body. 
 
     
     
       4. A tape cassette storing case according to  claim 1 , wherein the inclined surface is inclined in a longitudinal direction of the second side surface. 
     
     
       5. A tape cassette storing case according to  claim 1 , wherein the inclined surface is inclined in a lateral direction of the second side surface. 
     
     
       6. A tape cassette storing case according to  claim 1 , wherein each of the ribs comprises a first inclined surface in a longitudinal direction of the second side surface and a second inclined surface in a lateral direction of the second side surface. 
     
     
       7. A tape cassette storing case according to  claim 1 , further comprising a sheet member on the recess region. 
     
     
       8. A tape cassette storing case according to  claim 7 , wherein the sheet member has a coefficient of friction larger than any other portion than the sheet member in the tape cassette storing case. 
     
     
       9. A tape cassette storing case according to  claim 7 , wherein a height of the step is set to be greater than a thickness dimension of the sheet member. 
     
     
       10. A tape cassette storing case according to  claim 7 , wherein at least a portion of the sheet member formed of a resin is deposited in the recess region to form a sheet deposition portion, and the step comprises the sheet deposition portion. 
     
     
       11. A tape cassette storing case according to  claim 1 , wherein said plurality of ribs is provided at a predetermined interval. 
     
     
       12. A tape cassette storing case according to  claim 1 , wherein said second side surface is a rectangle having a pair of longitudinal sides and a pair of lateral sides, and said plurality of ribs is provided at a predetermined interval along a said longitudinal side of the second side surface. 
     
     
       13. A tape cassette storing case according to  claim 1 , wherein said second side surface is a rectangle having a pair of longitudinal sides and a pair of lateral sides, and said plurality of ribs is centered with respect to a said longitudinal side of the second side surface. 
     
     
       14. A tape cassette storing case according to  claim 1 , wherein said second side surface is a rectangle having a pair of longitudinal sides and a pair of lateral sides, said plurality of ribs comprises two or more groups of ribs, a first group of ribs is provided at a predetermined interval along one said longitudinal side, and a second group of ribs is provided at a predetermined interval along the other said longitudinal side of the second side surface. 
     
     
       15. A tape cassette storing case, comprising:
 a storing case main body for storing a tape cassette, the storing case main body having a first side surface and a second side surface that is opposite to the first side surface; 
 a recess region on the first side surface, the recess region being defined by a step from the first side surface; and 
 a plurality of ribs on the second side surface, 
 wherein when two storing case main bodies including a first main body and a second main body are stacked so that the first side surface in the first main body is superposed on the second side surface in the second main body, said plurality of ribs in the second main body is regulated by the step of the recess region on the first main body, and said plurality of ribs in the second main body each has an inclined surface with respect to the second side surface in the second main body, and 
 wherein said second side surface is a rectangle having a pair of said longitudinal sides and a pair of lateral sides, said plurality of ribs is centered with respect to a longitudinal side, and said plurality of ribs extends from one said longitudinal side to the other said longitudinal side of the second side surface.
